Neural agents trained in reinforcement learning settings can learn to communicate among themselves via discrete tokens, accomplishing as a team what would be unable do alone. However, the current standard of using one-hot vectors communication tokens prevents from acquiring more desirable aspects such zero-shot understanding. Inspired by word embedding techniques natural language processing, we propose neural agent architectures that enables them derived learned, continuous space. We show...
